Research Abstract

The purpose of this study is to determine the three-dimensional structures of transcription factors by X-ray crystallographic analysis, in order to understand the molecular mechanism of the DNA transcriptional regulation with RNA polymerase II. Transcription factors function as a complex of various kinds of proteins. To prepare the sample suitable for crystallization, the purification of the significant protein complex involved in transcriptional regulation was performed by using a co-expression system of E. coli and insect cells.
